Sorry for the late reply, but yes I bought the SU-16CA. I like it pretty much so far, but if they made one with a metal receiver, I'd trust that more. This is the first rifle I have shot that smelled like burning plastic when the barrel started smoking. (Modern ARs have metal shields between the barrel and handguard, so they smell like an overheating car, and my SKS smells like Cosmoline burning as the residual bits seep out of the stock.)
